Description

Technical Field

[0001] This application relates to the field of dough proofing, and more particularly to a dough proofing machine. Background Technology

[0002] Dough proofing refers to letting kneaded dough rest for a period of time before further processing or cooking. This process is called dough proofing. Proofing makes the kneaded dough easier to process, and the resulting pastries are more chewy, soft, and have a more delicate and smooth texture. In food processing and research, dough needs to be placed in a proofing machine for proofing.

[0003] In related technologies, dough proofing typically uses a simple fermentation box. This fermentation box usually has a basic structure and only has a basic heating device inside, which promotes dough fermentation by adjusting the temperature.

[0004] However, if the humidity inside the fermentation machine is insufficient, the dough surface is prone to forming a skin, resulting in poor fermentation. Summary of the Invention

[0005] To ensure the fermentation effect of the dough, this application provides a dough fermentation machine.

[0006] The dough fermentation machine provided in this application adopts the following technical solution: A dough fermentation machine includes a hollow proofing box with an inlet and outlet at the bottom. A water-absorbing component is installed at the upper part of the inside of the proofing box. A water spraying mechanism for spraying water onto the water-absorbing component is installed in the proofing box. A support plate for placing multiple placement boxes is rotatably connected inside the proofing box. The upper end of each placement box is open and the inside is used to place dough. The bottom surface of the water-absorbing component contacts the upper opening of each placement box. A drive mechanism for driving the support plate to rotate is connected to the support plate. A control mechanism for feeding or unloading the placement boxes near the inlet and outlet is installed on the proofing box.

[0007] By adopting the above technical solution, the inlet and outlet at the bottom of the proofing box facilitates the entry and exit of the placement boxes. The water spraying mechanism sprays water onto the water-absorbing components, keeping them moist. The bottom surface of the water-absorbing components contacts the upper opening of each placement box, providing a suitable humidity environment for the dough inside and ensuring the fermentation effect. The drive mechanism rotates the support plate, allowing the placement boxes that need to be discharged to be closer to the inlet and outlet for easy loading or unloading operations. The control mechanism can drive the placement boxes near the inlet and outlet to perform loading or unloading operations, realizing automatic entry and exit of dough from the proofing box, improving the efficiency and convenience of dough fermentation.

[0008] Preferably, the support plate has multiple mounting openings, and each mounting opening has a strip groove on its two side walls. The side wall of the placement box is fixedly connected to two placement blocks, each placement block corresponding to one strip groove. The placement blocks rotate around the axis of the placement box so that each placement block is inserted into the corresponding strip groove.

[0009] By adopting the above technical solution, rotating the placement box forward allows each placement block to accurately insert into the corresponding slot, achieving a stable installation of the placement box on the support plate; while rotating the placement box in reverse allows each placement block to disengage from the slot, making it easy to remove the placement box from the support plate. This method is convenient to operate and can effectively improve the efficiency of installation and disassembly of the placement box.

[0010] Preferably, the bottom wall of the proofing box is fixedly connected to a base frame, the control mechanism includes a hydraulic cylinder fixedly connected to the base frame, the piston rod of the hydraulic cylinder is vertically upward and fixedly connected to a control motor, the output shaft of the control motor is fixedly connected to a snap-fit ​​bracket, and the bottom wall of the placement box is provided with a snap-fit ​​groove for snapping with the snap-fit ​​bracket.

[0011] By adopting the above technical solution, when the dough fermentation machine is working, and it is necessary to unload the placement box near the inlet and outlet, the piston rod of the hydraulic cylinder on the base frame moves upward, pushing the locking frame connected to the control motor and its output shaft to rise, so that the locking frame engages with the locking groove on the bottom wall of the placement box. Then, the control motor starts, driving the placement box to rotate through the locking frame, thereby disengaging each placement block from its corresponding slot. At this time, the placement box is locked in place, and the unloading operation can be performed. The operation is simple and convenient. When loading the placement blocks, first, the locking frame engages with the locking groove on the placement box, then the hydraulic cylinder is started to drive the placement box to rise until the placement box is inserted into one of the installation ports and the placement box abuts against the water suction component. Then, the control motor is started to rotate the placement box until each placement block is inserted into its corresponding slot, at which point the installation of the placement box is completed.

[0012] Preferably, the support plate is equipped with a fall protection mechanism, which includes a fixed block fixedly connected to each slot, a transmission rod slidably inserted into each fixed block, a fall protection rod rotatably connected to each slot, a torsion spring installed between the fall protection rod and the support plate, one end of each transmission rod abutting the end of the fall protection rod extending into the slot, and each placement block slidingly inserting into the slot from the side of the transmission rod away from the fall protection rod and abutting the transmission rod. As the placement block gradually slides into the corresponding slot, the end of the fall protection rod away from the slot rotates to the bottom of the placement box and abuts the outer bottom wall of the placement box.

[0013] By adopting the above technical solution, an anti-fall mechanism is installed on the support plate. When the placement block slides into the slot from the side of the transmission rod away from the anti-fall bar and contacts the transmission rod, as the placement block gradually slides into the corresponding slot, the transmission rod moves under the push of the placement block, causing the anti-fall bar at one end of the transmission rod to rotate within the slot. Because a torsion spring is installed between the anti-fall bar and the support plate, the stability and reset function of the anti-fall bar's rotation are ensured. Finally, the end of the anti-fall bar away from the slot rotates to the bottom of the placement box and contacts the outer bottom wall of the placement box. This effectively reduces the occurrence of the placement box falling off the support plate, ensuring the stable placement of the placement box during dough fermentation and improving the safety and reliability of the dough fermentation machine. When the placement box rotates until the placement block gradually detaches from the corresponding slot, each anti-fall bar rotates and resets under the action of the torsion spring, disengaging from the placement box and facilitating smooth material discharge.

[0014] Preferably, a spring is sleeved on the outside of each of the transmission rods, with one end of the spring fixedly connected to the transmission rod and the other end fixedly connected to the fixing block.

[0015] By adopting the above technical solution, when the placement block is inserted into the strip groove, the placement block abuts against the transmission rod, causing the transmission rod to move and thus push the anti-fall rod to rotate to the bottom of the placement box and abut against the outer bottom wall of the placement box. The spring can provide buffering during the insertion of the placement block, limiting the transmission rod and the anti-fall rod from excessive impact. When the placement block is pulled out, the spring can drive the transmission rod to reset, so that the anti-fall rod returns to its initial position under the action of the torsion spring, which facilitates the disassembly and installation of the placement box.

[0016] Preferably, the absorbent component includes a mounting frame fixedly connected to the inner top wall of the proofing box, and a layer of absorbent cloth is fixedly connected to both the upper and lower surfaces of the mounting frame.

[0017] By adopting the above technical solution, the absorbent cloth is fixed on the upper and lower surfaces of the mounting frame, which can increase the water absorption area and provide a suitable humidity environment for dough fermentation.

[0018] Preferably, the water spraying mechanism includes a water spraying pipe fixedly connected to the inner top wall of the proofing box, a plurality of nozzles fixedly connected to the water spraying pipe, and one end of the water spraying pipe penetrating the side wall of the proofing box and extending to the outside of the proofing box.

[0019] By adopting the above technical solution, the water spray pipe is fixedly connected to the top wall of the proofing box, and has multiple nozzles that can spray water onto the water absorption components. One end of the water spray pipe extends through the side wall of the proofing box to the outside, making it easy to connect to a water source for continuous water supply, thus providing a suitable humidity environment for dough fermentation.

[0020] Preferably, the side wall of the proofing box is provided with an annular heating cavity, and a heating resistance rod is installed in the annular heating cavity.

[0021] By adopting the above technical solution, the annular heating cavity on the side wall of the proofing box and the heating resistance rod inside the cavity can heat the inside of the proofing box, providing a suitable temperature for dough fermentation and promoting dough fermentation.

[0022] Preferably, a door is hinged at the inlet and outlet, and a drive cylinder is hinged to the outer bottom wall of the proofing box, with the piston rod of the drive cylinder hinged to the outer side wall of the door.

[0023] By adopting the above technical solution, a hinged door is set at the inlet and outlet of the dough fermentation machine, and the door is driven by a drive cylinder hinged to the bottom wall of the proofing box. This enables the automatic opening and closing of the door, which facilitates the loading and unloading of the placement box into and out of the proofing box. At the same time, when the door is closed, it can maintain a relatively stable environment inside the proofing box, which is beneficial to the fermentation of the dough.

[0024] In summary, this application includes at least one of the following beneficial technical effects: It can provide a suitable humidity environment for the dough inside the box, ensuring the fermentation effect of the dough; This effectively reduces the occurrence of the placement box falling off the support plate, ensuring the stable placement of the placement box during dough fermentation; It facilitates the disassembly and installation of the storage box.

[0030] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0031] This application discloses a dough fermentation machine. (Refer to...) Figure 1 and Figure 2 The dough fermentation machine includes a hollow proofing box 1, a water-absorbing component 2, a water-spraying mechanism 3, a support plate 4, a drive mechanism 5, and a control mechanism 6. The water-absorbing component 2 is installed at the upper end inside the proofing box 1. The water-spraying mechanism 3 is installed in the proofing box 1 to spray water onto the water-absorbing component 2. The support plate 4 is rotatably connected inside the proofing box 1 and holds multiple placement boxes 7. The bottom surface of the water-absorbing component 2 contacts the upper opening of each placement box 7. The drive mechanism 5 is connected to the support plate 4 to drive the support plate 4 to rotate. The control mechanism 6 is installed on the proofing box 1 to drive the placement boxes 7 near the inlet / outlet 11 to feed or unload materials.

[0032] The water spraying mechanism 3 sprays water onto the water-absorbing component 2, keeping it moist. The water-absorbing component 2 covers the top of each placement box 7, providing suitable humidity for the dough and reducing the occurrence of crusting on the dough surface. The drive mechanism 5 drives the support plate 4 to rotate, allowing each placement box 7 to move towards the inlet / outlet 11, thus facilitating the loading and unloading of the placement box 7 by the control mechanism 6.

[0033] The water spraying mechanism 3 includes multiple water spray pipes 31 fixedly connected to the inner top wall of the proofing box 1. These pipes are interconnected, and each pipe is fixedly connected to multiple nozzles. One end of one pipe penetrates the side wall of the proofing box 1 and extends to the outside of the box. The pipe 31 is used to connect to a water source outside the proofing box 1 for continuous water supply. The pipes 31 are generally made of plastic, such as PVC, which is lightweight and corrosion-resistant. The nozzles can be atomizing nozzles, capable of evenly spraying water onto the absorber 2, or ordinary spray nozzles. The pipes 31 are fixed to the inner top wall of the proofing box 1 using clamps or similar methods, and the nozzles are fixed to the pipes 31 using threaded connections or similar methods. The combination of the pipes 31 and nozzles effectively sprays water onto the absorber 2, keeping it moist.

[0034] Reference Figure 1 and Figure 2The absorbent component 2 includes a mounting rod 21 fixedly connected to the inner top wall of the proofing box 1. A mounting frame 22 is fixedly connected to the lower end of the mounting rod 21. A layer of absorbent cloth 23 is fixedly connected to both the upper and lower surfaces of the mounting frame 22. The mounting frame 22 is typically made of metal, such as stainless steel, which has sufficient strength and corrosion resistance, allowing it to be securely installed on the inner top wall of the proofing box 1. The absorbent cloth 23 can be made of cotton, which has strong absorbency and low cost; alternatively, it can be made of fiber, which offers good absorbency and durability, and also provides good breathability.

[0035] The mounting bracket 22 is fixedly connected to the inner top wall of the proofing box 1 by bolts or other means, while the absorbent cloth 23 can be fixed to the mounting bracket 22 by adhesive or sewing. The combination of the absorbent cloth 23 and the mounting bracket 22 allows the absorbent cloth 23 to be stably held at a high position inside the proofing box 1, making it easy to contact the opening of the placement box 7 and provide moisture to the dough.

[0036] The drive mechanism 5 includes a rotating shaft 51 that is rotatably connected to the inner bottom wall of the proofing box 1, and the upper end of the rotating shaft 51 is fixedly connected to the middle of the support plate 4. A drive motor 52 is fixedly connected to the outer bottom wall of the proofing box 1, and the output shaft of the drive motor 52 passes through the bottom wall of the proofing box 1 and is coaxially fixed with the rotating shaft 51.

[0037] Start the drive motor 52. The output shaft of the drive motor 52 drives the rotating shaft 51 and the support plate 4 to rotate. The rotation of the support plate 4 drives the multiple placement boxes 7 to rotate, so that the placement boxes 7 that need to be unloaded can be aligned with the inlet and outlet 11.

[0038] Reference Figure 2 and Figure 3 The support plate 4 has multiple mounting ports 41, which are distributed around the circumference of the support plate 4. Each mounting port 41 has a slot 42 on its two side walls. The placement box 7 is located between the two slots 42. Two placement blocks 71 are fixedly connected to the side walls of the placement box 7. Each placement block 71 corresponds to one slot 42. The placement box 7 rotates around its axis so that each placement block 71 is inserted into the corresponding slot 42. By rotating the placement box 7 in the opposite direction by 45 degrees, each placement block 71 can be disengaged from the corresponding slot 42, thereby completing the disassembly of the placement box 7.

[0039] Reference Figure 1 and Figure 2 A base frame 8 is fixedly connected to the outer bottom wall of the proofing box 1. The control mechanism 6 includes a hydraulic cylinder 61 fixedly connected to the base frame 8. The piston rod of the hydraulic cylinder 61 is vertically upward, and a control motor 62 is fixedly connected to the upper end of the piston rod. The output shaft of the control motor 62 is vertically upward and fixedly connected to a snap-fit ​​bracket 63, which is cross-shaped. A cross-shaped snap-fit ​​groove 72 is provided on the outer bottom wall of the placement box 7 for snapping with the snap-fit ​​bracket 63.

[0040] Reference Figure 1 and Figure 2 When one of the placement boxes 7 that needs to be unloaded moves close to the inlet / outlet 11 and the locking slot 72 aligns with the locking frame 63, the hydraulic cylinder 61 is activated to drive the control motor 62 to rise until the locking frame 63 engages with the adjacent locking slot 72, and then the control motor 62 is activated. (Refer to...) Figure 2 and Figure 3 The output shaft of the control motor 62 drives the snap-fit ​​bracket 63 to rotate, which in turn drives the placement box 7 and the placement blocks 71 to rotate via the snap-fit ​​groove 72. The output shaft of the control motor 62 drives the placement box 7 to rotate forty-five degrees, causing each placement block 71 to disengage from its corresponding slot 42. (Refer to...) Figure 1 and Figure 2 The hydraulic cylinder 61 can be activated at any time. When the piston rod of the hydraulic cylinder 61 descends, it can drive the placement box 7 through the inlet and outlet 11 and separate it from the proofing box 1, thus completing the unloading of the placement box 7.

[0041] Reference Figure 1 and Figure 2 The proofing box 1 has an annular heating cavity 12 on its side wall, and a heating resistance rod is installed inside the annular heating cavity 12. The annular heating cavity 12 is a space reserved during the processing of the side wall of the proofing box 1. The heating resistance rod can be a ceramic heating resistance rod, which has high heating efficiency and long service life. The heating resistance rod is connected to a power source through wires, which can provide a suitable temperature inside the proofing box 1 to promote dough fermentation.

[0042] Doors 13 are hinged at the 11 entrances and exits. A drive cylinder 14 is hinged to the outer bottom wall of the proofing box 1, and the piston rod of the drive cylinder 14 is hinged to the outer side wall of the door 13. The door 13 can be made of metal, such as aluminum alloy, which is lightweight and has high strength. The drive cylinder 14 can open and close the door 13.

[0043] Reference Figure 3 and Figure 4 A fall arrestor 9 is installed on the support plate 4. The fall arrestor 9 includes a fixing block 91 fixedly connected in each strip groove 42. A transmission rod 92 is slidably inserted into each fixing block 91. A fall arrestor 93 is rotatably connected in each strip groove 42. A connecting shaft 94 is fixedly connected to the fall arrestor 93. A torsion spring 95 is sleeved on the connecting shaft 94. One end of the torsion spring 95 is fixedly connected to the fall arrestor 93, and the other end is fixedly connected to a cavity wall of the strip groove 42. A storage slot 43 is opened on both side walls of the mounting port 41. One storage slot 43 corresponds to one strip groove 42, and the storage slot 43 is connected to the strip groove 42. The storage slot 43 is used to store the fall arrestor 93.

[0044] One end of each transmission rod 92 abuts against one end of the anti-fall rod 93 that extends into the slot 42. A spring 96 is fitted onto the transmission rod 92, one end of which is fixedly connected to the fixing block 91, and the other end is fixedly connected to the transmission rod 92. Each placement block 71 slides into the slot 42 from the side of the transmission rod 92 away from the anti-fall rod 93 and abuts against the transmission rod 92. As the placement block 71 gradually slides into the corresponding slot 42, the end of the anti-fall rod 93 away from the slot 42 rotates to the bottom of the placement box 7 and abuts against the outer bottom wall of the placement box 7.

[0045] When the placement block 71 is inserted into the strip groove 42, it pushes the transmission rod 92 to slide, and the transmission rod 92 drives the anti-fall rod 93 to rotate, so that the anti-fall rod 93 rotates to the bottom of the placement box 7, which plays a role in preventing falls. When the placement box 7 is taken out, under the action of the torsion spring 95 and the spring 96, the anti-fall rod 93 and the transmission rod 92 return to their original positions. At this time, the anti-fall rod 93 rotates into the corresponding storage groove 43.

[0046] Once each placement block 71 has been inserted into the corresponding slot 42, the fall arrestor 93 and the locking bracket 63 do not interfere with each other.

[0047] Reference Figure 1 and Figure 2 An infrared transmitter 64 is fixedly connected to the inner bottom wall of the proofing box 1, and multiple infrared receivers 65 are fixedly connected to the support plate 4. The number of infrared receivers 65 is equal to the number of placement boxes 7 that can be installed on the support plate 4. When any infrared receiver 65 receives a signal emitted by the infrared transmitter 64, it means that the card holder 63 is aligned with the card slot 72 on the corresponding placement box 7, thus facilitating the alignment of the card holder 63 with the card slot 72 on the placement box 7. The infrared transmitter 64 and the multiple infrared receivers 65 are all electrically connected to the same controller, and the controller is electrically connected to the drive motor 52.

[0048] The implementation principle of a dough fermentation machine according to an embodiment of this application is as follows: When using the dough fermentation machine, the piston rod of the drive cylinder 14 first contracts, causing the door 13 to rotate around the hinge point and open the inlet and outlet 11. The piston rod of the hydraulic cylinder 61 of the control mechanism 6 extends, causing the snap-fit ​​bracket 63 to snap into the snap-fit ​​groove 72 on the bottom wall of the placement box 7 near the inlet and outlet 11. The control motor 62 is started to drive the snap-fit ​​bracket 63 and the placement box 7 to rotate. At this time, each snap-fit ​​block 71 on the placement box 7 disengages from the corresponding strip groove 42. The hydraulic cylinder 61 is started to drive the placement box 7 to descend. The placement box 7 passes through the inlet and outlet 11 and leaves the interior of the proofing box 1, thus completing the unloading of the placement box 7.

[0049] During the proofing process, the heating resistance rod inside the annular heating chamber 12 is energized and heats up, providing a suitable temperature inside the proofing box 1. The water spraying mechanism 3's spray pipe 31 supplies water from an external water source, and the nozzle sprays water onto the water-absorbing component 2. The water-absorbing cloth 23 of the water-absorbing component 2 remains moist, ensuring that each placement box 7 is in a humid environment, providing suitable humidity for dough fermentation. After fermentation is complete, the drive cylinder 14 opens the door 13, and the control mechanism 6 repeats the above actions to perform the feeding operation.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
